1 Claim.

This invention relates to metal hollow ware, as for instance, candlesticks, table lamps, candy dishes and the like, and more particularly tothe type having base filled with a cement or plaster which hardens intoa solid mass.

This manner of construction is prevelant in the manufacture of sucharticles made of thin gage precious metal sheeting formed into shells ofvarious shapes and decorative forms, which are suitably joined to make aunitary structure. The base shell carries a bottom cover member, whichheretofore was mounted after the base shell was filled; the said covermember and the base shell being associated by a clinching operation.

One of the objects of this invention is to eliminate such clinchingoperation.

In electric table lamp construction in this class of merchandise, anelectric cord-carrying tube or nipple is carried projecting upwardlyfrom the base shell. It is essential that such tube be fixed withrespect to the base and not become loosened.

Another object of the present invention is to provide a novel andimproved construction by which such tubular member is securely anchored.

To accomplish these objects, I provide novel and improved constructionsby which the filler is utilized to maintain secure and rigid assembly ofthe components. These constructions are reasonably cheap to practice,convenient and easy in manufacture and eflicient in carrying out thepurposes for which they are designed.

Other objects and advantages will become apparent as this disclosureproceeds.

In the accompanying drawings forming part of this specification, similarcharacters of reference indicate corresponding parts in all the views.

Fig. 1 is a central vertical section of an electric table lamp embodyingthe teachings of this invention. The base, per se, may be deemed that ofa candle stick or of any other article of this class of merchandise.

Fig. 2 is a bottom view of Fig. 1, minus the bottom cover member, andwithout the cement filler.

Fig. 3 is an exploded view of parts included in Fig. 1 and shown incentral section.

Fig. 4 is a fragmentary sectional view showing an old type of joint ofhow the bottom member may be joined to the base shell.

Fig. 5 is a view similar to Fig. 4, of another type of old joint.

Fig. 6 is an enlarged fragmentary sectional view of one construction Iprovide herein for securing the assembly of the base shell and itsbottom cover member.

Fig. 7 is similar to Fig. 6, and shows a modified form of constructionto accomplish the same purpose.

Fig. 8 is another modified form thereof.

In the drawings, the numeral l6 denotes the shell and the numeral 11,its bottom cover member, which together form the base of a hollow warearticle such as a candle stick, candy dish and the like, or asspecifically shown in Fig. 1, the base of an electric table lamp l8.Said shell and cover member are spun or stamped of thin gage sheetmetal, which in my trade is usually sterling silver. To lend theattributes of a solid mass, the shell I6 is filled with a suitablecompound known in this art as cements or plasters I9. After suchfilling, assembly of components l6 and I! was heretofore accomplished bya clinched joint in the nature of those illustrated for instance in theFigs. 4 and 5, usually performed by a lathe operation. In Fig. 4, thebottom cover member denoted by the numeral I I1, is clinched over thehead 20 around the shell H6, while in Fig. 5, the shell M6 is clinchedover the bead 2| around the bottom cover member 2.

In particular, I provide a novel construction which needs no clinchingoperation to associate the shell and its bottom cover member. I have themembers M6 and 3H in telescopic fit as shown in Fig. 6, or I have themembers 416 and M1 in telescopic fit as shown in Fig. '7, or else, thecover member 5|! may be flush plug-fit in the shell SIG, at the base ofthe latter as in Fig. 8. To accomplish proper assembly, I rely uponmeans embedded in and which becomes anchored in the filler IS. The covermember may be formed with exterior annular channel 23 and be imbedded inthe filler as is the base member 4|! shown in Fig. '7, or in saidembodiment I may provide the interior annular channel 23', omittingchannel 23, but employing the button 22. In the other embodiments, suchbutton alone is utilized to maintain the assembly of the basecomponents.

Such anchoring member 22 may be a separate button comprising a bodyhaving flanged ends. Such end as resides within the plaster, meaning theflange 24, is of a size less than the central hole 25 in the bottomcover members, and the flange 26 at the other end of the button 'body21, is of a comparatively larger size than said hole or opening, so asto completely cover such hole and set on annular seat 28. It is evidentthat to accomplish anchorage, instead of the flange 24, the button bodymay have any lateral projection 01' projections within the plaster orcement l9. If desired, as in Fig. 8, the anchorage member 22' may beintegral with, or in any suitable manner secured to the bottom basecover member.

When the base is for a lamp as in Fig. 1, the usual nipple or othertubular member as 29, may be slit up from the bottom, to form a pair ofwings 30, which are bent laterally of the axis of said tubular member toafford anchorage means for such member when the plaster hardens. Sinceassembly of the components shown in Fig. 1, needs no lathe operation,but is entirely performed at the bench, the electric cord may bethreaded through opening 3! and through the tubular member 29, beforethe shell is filled. Although such cord is not shown, its placement ireadily understood to those versed in this art, without furtherillustration.

Any two pants as 32 and 33 can be assembled without clinching, and relysolely upon anchorage achieved in a cement fill H9 in one of them intowhich the other is pushed; the shell being formed with annular bead 32and the other member with a similar bead 33, to accomplish properanchorage and assembly upon the setting of the cement. As shown in Fig.1, parts 32 and 33 are of a storm lamp; part 33 being adapted to hold aglass chimney, while an electric socket sets on the nipple 29; saidchimney and socket being not shown to attain clarity of illustration ofthe components pertinent to this invention. Dimensions of the parts areof course made to suit any intended purpose.

This invention is capable of numerous forms and various applicationswithout departin from the essential features herein disclosed. It istherefore intended and desired that the embodi- :lli

4 ments set forth herein be deemed illustrative and not restrictive andthat the patent shall cover all patentable novelty herein set forth;reference being had to the following claim rather than to the specificdescription herein to indicate the scope of this invention.

I claim:

In a hollow ware article of the character described, a shell having anopen mouth, a cover member positioned across said mouth; said covermember having a hole therethrough; the perimeter of said hole being theinner edge of an annular seat depressed in the cover member in thedirection into the shell, a self -hardening filler filling said shelland a separate member covering said hole and extending into the filler,anchored by said filler when said filler hardens and adapted when soanchored, to maintain the shell and cover member in assembled condition;said separate member comprising a shank having a lateral flange at oneend and a lateral extension at its other end; said lateral extensionbeing capable of being entered through said hole in the cover memher andsaid flange being larger than said hole and adapted to set on said seatwhen the shank is pushed through said hole into the filler.
